What is the Features of TP347 Polished Tube?

TP347 stainless steel tube is typically made from 18-8 stainless steel with alloying elements such as Niobium and Titanium. These alloying elements provide improved resistance to heat and corrosion, especially in high temperature environments. TP347 tubes are similar to TP321 tubes, but have better resistance to weld intergranular corrosion. As a result, they are widely used in high-temperature, highly corrosive environments, such as the chemical, oil and gas industries. TP347 stainless steel tubing is considered an ideal choice because of its properties that provide stability and durability in a variety of high-temperature and corrosive conditions.



The Polished Process:

The metal pipeline undergoes a surface polishing process that enhances its appearance and performance through mechanical or chemical treatments. This process involves two main methods: mechanical and chemical polishing.

In mechanical polishing, multiple grinding and polishing stages use varying abrasive particle sizes to progressively refine the metal's surface until achieving the desired smoothness and shine. Employing abrasives and grinding media, the process utilizes rotating or vibrating tools.
Chemical polishing involves applying acidic or alkaline solutions onto the metal surface to eliminate oxidation layers and irregular impurities, commonly utilized for materials like stainless steel, copper, and aluminium.
Enhancing the lustre and smoothness of metal pipes, the polishing process not only improves their visual appeal but also boosts their resistance to corrosion, ease of cleaning, and suitability for specific applications.


Polished Stainless Pipe

Stainless steel polished pipes are used in a wide range of applications. In the chemical and petroleum industries, their excellent corrosion resistance makes them ideal for the transportation of corrosive liquids. In the food and beverage industry, the smooth surface of polished pipes helps to clean and sanitize, meeting stringent hygiene standards. In addition, stainless steel polished pipes are widely used in decorative and architectural applications, such as hotel lobbies and shopping mall display cases, adding beauty and ambience to the space with their elegant appearance and modernity.

 

With its excellent performance, elegant appearance and diverse applications, stainless steel polished pipes offer new possibilities and flexibility for a wide range of industries. No matter what your project needs are, polished pipes may be the ideal choice for you.
